Embodiment 1

[0016] Such as figure 1 As shown, a water heater water-saving system includes a hot water outlet pipe (1), a first pipeline (2), a water tank (3) and a first valve (4), and one end of the hot water outlet pipe (1) is connected to The water heater (5) is connected, the other end is connected with a water inlet (15) of the indoor three-way regulating valve (6), the other water inlet of the three-way regulating valve (6) is connected with the tap water pipe (7), and the first pipeline One end A of (2) communicates with the hot water outlet pipe (1), the other end B communicates with the water tank (3), and the end A communicates with the water inlet (15) of the hot water outlet pipe (1) of the three-way regulating valve (6). The length of the hot water outlet pipe between ) is not more than 1 meter, the first valve (4) is arranged on the first pipeline (2), and the upper part of the water tank (3) has an opening (8) to communicate with the atmosphere. The first valve (4) is in a...

Embodiment 2

[0018] Such as figure 2 As shown, a water heater water-saving system also includes a water pump (9) on the basis of Embodiment 1, the water heater (5) is a non-pressurized solar water heater, and the water pump (9) is located in the first pipeline (2 ), and the water flow direction of the water pump (9) is that water flows from end B to end A along the first pipeline (2) when the water pump (9) is turned on. Before using hot water, the temperature of the water in the hot water outlet pipe (1) is relatively low. Open the first valve (4), and the low temperature water in the hot water outlet pipe (1) will flow from end A to end A along the first pipeline (2). B, enter in the water tank (3) at last. When the water temperature at the end A is higher, after reaching the water temperature requirement for bathing, close the first valve (4). As the water level of the water tank (3) rises, the upper air in the water tank (3) is discharged into the atmosphere from the opening (8) on ...

Embodiment 3

[0020] Such as image 3 As shown, a water heater water-saving system, on the basis of Embodiment 2, also includes a second pipeline (10) and a second valve (11), one end C of the second pipeline (10) and the first pipe The road (2) communicates between the first valve (4) and the water pump (9), the other end D is connected to the tap water pipe (7), and the second valve (11) is arranged on the second pipeline (10), The first valve (4) and the water pump (9) are sequentially arranged from end B to end A on the first pipeline (2). Some users of non-pressurized solar water heaters have a large height difference between floors and roofs. When only relying on the pressure of tap water for water supply, the water supply pressure is insufficient and the water supply speed is very slow. At this time, a water pump needs to be installed to pressurize the water supply. The present invention sets up a water pump (9) when solving the problem of waste of water resources in the non-pressur...

Abstract

The invention discloses a water heater water-saving system. One end A of a first pipeline is in communication with a hot water outlet pipe, the other end B of the first pipeline is in communication with a water tank, a first valve and a water pump are arranged on the first pipeline, an opening is formed in the upper part of the water tank and is in communication with the atmosphere, and the firstvalve is in a normally closed state. Before hot water is used, the first valve is opened to discharge low-temperature water in the hot water outlet pipe into the water tank. After the hot water is used, the first valve and the water pump are opened, and the water in the water tank is pumped back to the water heater. A second pipeline is additionally arranged, and the water pump can be used for pressurizing so as to supply water to the non-pressure-bearing solar water heater. The opening is connected to an automatic exhaust device to prevent the water from overflowing from the water tank. The first valve is an electromagnetic valve, the upper part of the water tank is provided with a liquid level sensor, the electromagnetic valve and the liquid level sensor are connected to the controller,and the water level in the water tank is limited by the controller. According to the water heater water-saving system, the problem of water resource waste caused by low-temperature water in the hot water outlet pipe is discharged before the water heater is used is solved, the operation is simple and convenient, and the cost is low.

Description

Technical field: [0001] The invention relates to the technical field of water heaters, in particular to a water-saving system for water heaters. Background technique: [0002] There is generally a distance between the water heater and the three-way regulating valve at the indoor water point. Before using hot water, the water temperature in the hot water outlet pipe between the water heater and the three-way regulating valve of the indoor water point is low, which cannot meet the temperature requirements of bathing water. The low-temperature water in the pipe should be drained first, and continue to drain until the water comes out It can only be used after the temperature reaches the water temperature requirement, which causes the problem of waste of water resources. Household non-pressurized solar water heaters are installed on the roof, and the length of the hot water outlet pipe is as short as several meters and as long as tens of meters. The gas or electric water heater...
